I-375 was built as a gateway to Downtown Detroit in 1964. After 50 years of use, it needs to be reconstructed. MDOT is deciding what to do with the I-375 corridor and the I-75/I-375/Gratiot Connector interchange.

SCREENING PROCESS

6 Illustrative AlternativesSix Illustrative Alternatives from the

2014 PEL Study were examined

Screening ProcessA screening process scored how each Illustrative

Alternative met the project’s Purpose & Need

2 Practical AlternativesTwo Practical Alternatives developed from the

highest scoring Illustrative Alternatives

2014 Planning and Linkages StudyThe 2014 Planning and Linkages (PEL) Study, the I-375 Alternatives

Study, identified a Purpose and Need for the project

MDOT will hold a public hearing to present the social, economic, and environmental impacts of the two

Practical Alternatives that will ultimately lead to a decision of the

Preferred Alternative.

Refinements made based on public feedback and detailed technical environmental analysis
